The Haptic Feedback Shift Knob is a replacement for a manual transmission shift knob that adds haptic and visual feedback to help drivers shift appropriately. An Android application monitors the vehicle’s speed, RPM and accelerator pedal position. Based on this information, the application calculates and then indicates to the driver when he or she should shift by vibrating the shift knob. After feeling the haptic “pulse” the driver can then appropriately respond. The embedded electronics in the shift knob are based on the Arduino Pro Mini with an on-board FTDI chip and USB connector. The Shift Knob was originally designed and developed by Zac Nelson at Ford.
